CloseHandle Error!!

[Adam Shapiro]

I am using Rob's serial port method in Dashboard3D and everything is working well (I'm about half done) but when I go to close the port, the CloseHandle function never returns! The code is as follows:

HANDLE hSerial; //Opened in the constructor with CreateFile, etc.
CSerial::~CSerial(){CloseHandle(hSerial);}

I have debuged it up to that point so it does get to the CloseHandle function but it never passes. It took me two days to even figure out why the process wouldn't end in WinXP! Any suggestions? (I don't want to "just leave it open"...)
